AI Technical Summary

Technical Problem

Existing inter-process communication methods in Linux systems pose a security risk of information leakage. Attackers can exploit kernel vulnerabilities to view arbitrary kernel data structures and bypass permission control mechanisms such as SELinux, leading to the leakage of private information.

Method used

The asymmetric key pair is obtained through a key negotiation service. The process registers and establishes a temporary secure channel through the key negotiation service, generates a shared session master key for encrypted transmission, and destroys the key material after the communication ends. The key negotiation logic is centralized in the trusted service to avoid kernel modification.

Benefits of technology

It improves the security of inter-process communication, prevents attackers from cracking communication ciphertext, is compatible with various systems, does not require modification of the system kernel, and enhances security and compatibility.

Abstract

The present disclosure provides an encrypted inter-process communication method, system, computer device and medium. The method comprises: a key negotiation service obtaining and holding an asymmetric key pair; a first process and a second process registering with the key negotiation service respectively by using the asymmetric key pair, and establishing a temporary secure channel between the key negotiation service and the first process and the second process respectively; the key negotiation service generating a shared session master key for the first process and the second process, and distributing the session master key to the first process and the second process through the temporary secure channel; and the first process and the second process performing encrypted transmission of inter-process communication data based on the session master key. The encrypted inter-process communication method of the present disclosure can achieve lightweight and secure communication between processes of different systems.
